Update xla download script

[vfdev-5]

@Priyansi your script to download torch xla is not working for 1.10

# install torch-xla
VERSION = !curl -s https://api.github.com/repos/pytorch/xla/releases/latest | grep -Po '"tag_name": "v\K.*?(?=")'
VERSION = VERSION[0].rstrip('.0') # remove trailing zero
!pip install cloud-tpu-client==0.10 https://storage.googleapis.com/tpu-pytorch/wheels/torch_xla-{VERSION}-cp37-cp37m-linux_x86_64.whl

It gives 1.1

Could you please fix and update it. Thanks
